Mount Polley operations have been suspended, and as of May 31, 2019, the mine is on care & maintenance status. A resumption of operations is anticipated once the economics of mining at Mount Polley improve.

Extensive remediation work in the areas affected by the 2014 breach has been achieved during the past five years. The mine’s closure will not impact the ongoing environmental monitoring and remediation programs.

During Spring 2018, a four hole diamond drill program was completed totalling 953.12 metres. The holes were drilled in the Saddle area between the Springer and Cariboo pits to confirm mineralization in this area for future mining plans. This information has been incorporated into the mine’s block model.

An exploration program has been designed to target the mineralization underneath the Saddle zone, separating the Cariboo and Springer Phase 6 pits. This represents an ideal opportunity to find additional low stripping ratio reserves for when mine operations re-start. This exploration is planned following suspension of mine operations.

A program of ground magnetometer surveying, started in 2018, will continue in 2019 in conjunction with targeted areas of soil sampling, prospecting and geological mapping. Future additional diamond drilling of targets in the vicinity of the Springer pit is also planned. The set exploration targets have been identified by a combination of soil sampling and geophysical surveys.

Mount Polley is an open pit copper/gold mine with an underground component located in south-central British Columbia, 56 kilometres northeast of Williams Lake. The property encompasses 20,113 hectares, comprised of seven mining leases totalling 2,007 hectares, and 46 mineral claims encompassing 18,106 hectares. Mount Polley mine is owned and operated by Mount Polley Mining Corporation (MPMC), a subsidiary of Imperial.
